2025-07-22soc: qcom: geni-se: Enable QUPs on SA8255p Qualcomm platformsPraveen Talari
On the sa8255p platform, resources such as clocks,interconnects and TLMM (GPIO) configurations are managed by firmware. Use the `num_clks` field in platform data to distinguish whether resource control is performed by firmware or directly by the driver in linux.

2025-07-22comedi: fix race between polling and detachingIan Abbott
syzbot reports a use-after-free in comedi in the below link, which is due to comedi gladly removing the allocated async area even though poll requests are still active on the wait_queue_head inside of it. This can cause a use-after-free when the poll entries are later triggered or removed, as the memory for the wait_queue_head has been freed. We need to check there are no tasks queued on any of the subdevices' wait queues before allowing the device to be detached by the `COMEDI_DEVCONFIG` ioctl. Tasks will read-lock `dev->attach_lock` before adding themselves to the subdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctl handler by write-locking `dev->attach_lock` before checking that all of the subdevices are safe to be deleted. This includes testing for any sleepers on the subdevices' wait queues. It remains locked until the device has been detached. This requires the `comedi_device_detach()` function to be refactored slightly, moving the bulk of it into new function `comedi_device_detach_locked()`. Note that the refactor of `comedi_device_detach()` results in `comedi_device_cancel_all()` now being called while `dev->attach_lock` is write-locked, which wasn't the case previously, but that does not matter. Thanks to Jens Axboe for diagnosing the problem and co-developing this patch.

2025-07-22sunvdc: Balance device refcount in vdc_port_mpgroup_checkMa Ke
Using device_find_child() to locate a probed virtual-device-port node causes a device refcount imbalance, as device_find_child() internally calls get_device() to increment the device’s reference count before returning its pointer. vdc_port_mpgroup_check() directly returns true upon finding a matching device without releasing the reference via put_device(). We should call put_device() to decrement refcount. As comment of device_find_child() says, 'NOTE: you will need to drop the reference with put_device() after use'. Found by code review.

Octeontx2/CN10k MAC block supports DMAC filters. DMAC filters can be installed on the interface through ethtool. When a user installs a DMAC filter, the interface's MAC address is implicitly added to the filter list. To ensure consistency, this MAC address must be kept in sync with the pfvf->mac_addr field, which is used to install MAC-based NPC rules. This patch updates the pfvf->mac_addr field with the programmed MAC address and also enables VF interfaces to install DMAC filters.

2025-07-22ibmveth: Add multi buffers rx replenishment hcall supportMingming Cao
This patch enables batched RX buffer replenishment in ibmveth by using the new firmware-supported h_add_logical_lan_buffers() hcall to submit up to 8 RX buffers in a single call, instead of repeatedly calling the single-buffer h_add_logical_lan_buffer() hcall. During the probe, with the patch, the driver queries ILLAN attributes to detect IBMVETH_ILLAN_RX_MULTI_BUFF_SUPPORT bit. If the attribute is present, rx_buffers_per_hcall is set to 8, enabling batched replenishment. Otherwise, it defaults to 1, preserving the original upstream behavior with no change in code flow for unsupported systems. The core rx replenish logic remains the same. But when batching is enabled, the driver aggregates up to 8 fully prepared descriptors into a single h_add_logical_lan_buffers() hypercall. If any allocation or DMA mapping fails while preparing a batch, only the successfully prepared buffers are submitted, and the remaining are deferred for the next replenish cycle. If at runtime the firmware stops accepting the batched hcall—e,g, after a Live Partition Migration (LPM) to a host that does not support h_add_logical_lan_buffers(), the hypercall returns H_FUNCTION. In that case, the driver transparently disables batching, resets rx_buffers_per_hcall to 1, and falls back to the single-buffer hcall in next future replenishments to take care of these and future buffers. Test were done on systems with firmware that both supports and does not support the new h_add_logical_lan_buffers hcall. On supported firmware, this reduces hypercall overhead significantly over multiple buffers. SAR measurements showed about a 15% improvement in packet processing rate under moderate RX load, with heavier traffic seeing gains more than 30% Signed-off-by: Mingming Cao <mmc@linux.ibm.com> Reviewed-by: Brian King <bjking1@linux.ibm.com> Reviewed-by: Haren Myneni <haren@linux.ibm.com> Reviewed-by: Dave Marquardt <davemarq@linux.ibm.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20250719091356.57252-1-mmc@linux.ibm.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
